Answer:
Explanation:
Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.
The reduction is accomplished by 2 divisions after the duplication of chromosomes
- first division: separation of homologous pairs of chromosomes (this reduces the total in half)
- second division: separation of sister chromatids of a chromosome.
The rearrangement in meiosis occurs by crossing over/genetic recombination.
This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation
An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.
This condition produces offsprings that have some characteristic facial features, short stature etc
The types are Blackwater, Graywater and Yellow water.
You can find two types of wastewater: household sewage and wastewater
Answer:
C
Explanation:
Humans are the most evolved species in the phylogeny
Phylogeny in biology pertains to the evolutionary history or development of a group of organisms, such as a tribe or a racial group.
Human happen to be at the top of this evolutionary history
<span>Based on the diagnosis, the nurse
anticipates that there will be a component of the treatment plan is supportive.
More severely ill children may be hospitalized and given oxygen, chest
physiotherapy, and IV fluids. Antibiotics are not given. Bacterial pneumonia,
however, is treated with antibiotic therapy.</span>
D because this is the process of when the nitrogenous bases are going to match each other to form our DNA sequence
